Bolster health means doing things to help keep your body strong and healthy. Just like you need to eat good food, get plenty of rest, and exercise to keep your body strong, there are other things you can do to bolster your health too.
For example, washing your hands with soap and water can help keep germs from spreading and making you sick. Wearing a helmet when you ride your bike or scooter can help protect your head if you fall. And going to the doctor for checkups and shots can help make sure you stay healthy and don't get sick.
Bolstering your health can help you feel good, have more energy, and be able to do all the fun things you want to do every day!
